DESCRIPTION
HINT:
"Door side airbag sensor LH" refers to the side airbag sensor LH.
-
The side airbag sensor LH or rear airbag sensor RH consists of the safing sensor, the diagnostic circuit, the lateral deceleration sensor, etc.
If the center airbag sensor receives signals from the lateral deceleration sensor, it determines whether the SRS should be activated.
DTC B1630/23 or B1695/16 is stored when a malfunction is detected in the side airbag sensor LH or rear airbag sensor RH circuit.
